Top Table Large for the Rack of Silence.
Available in black and white painted MDF or veneered Sandwich board.
Integrated flush mounted Spirit Level.
Allows for placement of a turntable with separate motor and plinth.
The painted MDF board dimension is 695 x 520 x 22mm and weight is 6 kg.
The veneered sandwich board consists of 4 layers:
- Layer 1: thin sheet of cork on the top to avoid any potential ringing in the table
- Layer 2: MDF
- Layer 3: Porous damp layer that will absorb and remove resonance in the table
- Layer 4: MDF
The Sandwich table in veneer has a thickness of 24mm width of 527mm and a length of 705mm. The board has been tested by letting a 9,8g steel ball be dropped 50 cm above the sandwich board and compared with a standard MDF board. The result is described in below table:
|Peak value (dB)
|Peak average over 3 seconds (dB)
|Standard MDF board
From the result one can read that the sandwich board basically damp with 10-13dB compared to a standard MDF board.
The large top tables have a limitation of load as it is placed on top of the corner pillars of the Rack of Silence and thus only supported in the corners. The maximum load is 50kg for the sandwich shelves and 60kg for the white and black MDF shelves. If further load is required it is recommended to place the uppermost rack shelf just beneath it and use the apparatus support to assist the support of the table. In this way the maximum load can be increased to 160kg.
